OBTAINING MULTI-COMPONENT CHROME COATINGS ON PARTS THAT ARE USED IN AGGRESSIVE CONDITIONS OF ELASTOMER PRODUCTION

Abstract

This research is devoted to the study of the technology for obtaining multicomponent chrome coatings on parts that operate under aggressive conditions of elastomeric production. In particular, the use of the self-propagating high-temperature synthesis (SHS) method is considered, which allows obtaining coatings with high corrosion resistance due to the formation of passive oxide films on the surface. The urgency of the problem of increasing the reliability and durability of parts under aggressive conditions is analyzed, which indicates the need to introduce effective methods of protecting machines and installations. The article considers the methodology for obtaining multicomponent chrome coatings using SHS technology, as well as the effect of thermal spontaneous combustion with dilution of the powder mixture on the efficiency of coating production and their corrosion resistance. The corrosion resistance of the obtained coatings in aggressive environments, such as an aqueous solution of hydrochloric acid, nitric acid, and sulfuric acid with a concentration of 15%, was studied. Based on the research results, it is concluded that the use of multicomponent chrome coatings is effective for improving the corrosion resistance of parts that operate in aggressive conditions of elastomer production. This article is of practical importance for increasing the durability and reliability of machines and installations, especially in the conditions of elastomer production, where the resistance of parts to aggressive environments and corrosion is important.
